Question

A student made a model of isostasy by placing a block of wood in a beaker of water. What does the wooden block represent in the model?
A. A glacier
B. Earth's crust
C. Sea level
D. Earth's mantle

Answer 1

I am almost positive the answer is B, Earth's crust. I know it cannot be A or C because isostasy has nothing to do with sea level or glaciers, and Earth's mantle is inside.

Answer 2

Answer:

The correct option is: B. Earth's crust

Explanation:

Isostasy refers to the state of gravitational equilibrium at which the outermost solid layer, called the crust, floats on the underlying layer, called the mantle of the Earth.

In the given isostasy model made by the student, water in the beaker represents the Earth's mantle and the floating wooden block represents the Earth's crust.
